Petralens is an iPhone field notebook for exploring rocks and minerals. Take a photo to see a possible visual match, the clues behind it, similar looking alternatives, and simple observations to try next.
A photograph alone cannot confirm a mineral identification, authenticity, origin, or value. The first valid rock analysis is free; Pro offers more analyses, subject to a daily service limit. The photo field notebook stays on your iPhone.

No. Petralens gives a cautious visual suggestion. A photo alone cannot verify a mineral's identity, origin, authenticity or value.
A photo is sent to a cloud analysis service only when you ask for analysis; the service does not store it. Your saved field notebook stays on your iPhone.
Pro unlocks more photo analyses after the first valid result, subject to a 15-scan daily limit per installation. Weekly, monthly, yearly and lifetime options are planned; the yearly plan offers a 7-day trial to eligible customers.
